Yep its a scam... he transfered most funds to other final accounts already, one with over 11.000 ethereum...

Its stupid because if he let things run smooth for the time it was supposed he would get much more money from it as others would advertise the system...  Tho he scams people in 1 day, run with few ether and dont earn anything else...

Theres no way others can make money if the contract transfers 99% of the ether to his own account.

He could use the time to do something usefull other than scam...

I bet he is the one that transfer most funding from outsorced wallets to make people think others are really getting paid.

Remember Scammer the Karma can come into several ways ! Just wait for it!
